Bosch and Volkswagen are working together to carry out their autonomous driving projects in parallel. In this sense, the sharing of data provided by cars is essential to allow greater system security, but the timeliness of updates is equally important.
Testing continues aboard the eighth generation Volkswagen Golf. “As they travel, these vehicles are capable of providing information for Bosch’s road mapping service. The cloud-based location application uses real-world traffic data detected by sensors to create and update multi-level maps in high resolution“Explains Bosch.

Moreover, in order for cars to drive on their own in the future, they will need hyper-detailed digital maps, in which the location must be millimeter. Bosch’s mapping service processes information from radar and video sensors and vehicle motion data, adds layers to common navigation maps allowing for vehicle tracking and control. The new map levels are expected to be applied mainly to vehicles with autonomous driving functions of level 2 and above, but they also offer advantages at lower levels.
“While on the road, the fleet uses environmental sensors to generate information about landmarks, such as road signs, guard rails, curbs and road markings. The vehicles send data to the Bosch cloud via the VW cloud completely anonymously. In addition, only the information necessary for the map layers is transmitted. On that basis, the road mapping service is created in the Bosch cloud, which is a sort of digital twin of the real environment. In real time, each vehicle compares the information provided by the environmental sensors with that of its digital twin. Thanks to the use of radar, the location works reliably even in
adverse weather conditions, such as fog, rain and snow, which make it difficult, if not impossible, for the camera to perceive the surrounding environment“, Bosch declares.
